Comparative study on combustion and oxy-fuel combustion environments using mixtures of coal with sugarcane bagasse and biomass sorghum bagasse by the thermogravimetric analysis
Biomass and coal have different physicochemical properties and thermal behavior. During the co-combustion of coal-biomass mixtures, their thermal behavior varies according to the percentage of each fuel in the mixture. ...
Allometric relations for biomass partitioning of Nothofagus antarctica trees of different crown classes growing in a site quality gradient
(Elsevier Science, 2010-03)
Data on tree biomass are essential for understanding the forest carbon cycle and plant adaptations to the environment. We determined biomass accumulation and allometric relationships in the partitioning of biomass between ...
Cattle and goat grazing on the herbaceous cover of a lowered caatinga.
(In: INTERNATIONAL CONFERENCE ON GOATS, 4., 1987, Brasília, DF. Proceedings... Brasília, DF: EMBRAPA-DDT, 1987. v. 2, p. 1431. Resumo 184, 1987)
Diurnal variation of zooplankton biochemical composition and biomass in plankton production tanks
The nutritional value of zooplankton (lipid and phosphorus contents) was analyzed in outdoor, plankton-culture tanks, to monitor the effects of diurnal variation and fertilization. Total lipid contents were significantly ...
A comparison between traditional ordinary least-squares regression and three methods for enforcing additivity in biomass equations using a sample of Pinus radiata trees
Background: Additivity has long been recognised as a desirable property of systems of equations to predict the biomass of components and the whole tree. However, most tree biomass studies report biomass equations fitted ...
Simplified Model And Simulation Of Biomass Particle Suspension Combustion In One-dimensional Flow Applied To Bagasse Boilers
(Pergamon-Elsevier Science LTDOxford, 2017)
Experimental aspects of biomass fuels in a bubbling fluidized bed combustor
(Elsevier B.V. Sa, 2008-09-01)
This work presents experimental information relevant to the combustion of biomass in a bubbling fluidized bed. The biomass distribution in a fluidized bed was studied through tests performed in a cold bed, while the volatiles ...
Biomass partitioning and leaf area of Pinus radiata trees subjected to silvopastoral and conventional forestry in the VI region, Chile
(Sociedad de Biología de Chile, 2003)
Prediction of the combustion process in fluidized bed based on physical-chemical properties of biomass particles and their hydrodynamic behaviors
(Elsevier B.V., 2014-08-01)
The utilization of biomass in fluidized bed reactors is due to alternatives created by the carbon credit market and to environmental concerns. This fact calls for an accurate determination of physical-chemical properties ...
